I used the procedure "Conversion of NIRx NIRScout data format to SPM-fNIRS data format" by using the .wl1 , .wl2 and .hdr files. And this worked for me but when click spatial and try to upload files it suggests I use a .csv file. I collected my data using nirs star/nirs lab and am now trying to process in spm. The raw data file folder doesn't have any csv files. It does have config.txt, probe_info.txt, .dat, .hdr, .mat, .avg, and more. Does anyone know which files I need to use for this step or what works. I keep getting an error.
